Caught between the presidential candidacies of Republican Donald Trump and Democrat Hillary Clinton, a group of Christians is choosing a third way out: prayer.

Get Out the Prayer 2016 is mobilizing believers to influence the political process not only with their votes, but through appeals to a higher authority.

Dave Kubal, president of Intercessors of America, which is spearheading the effort, said Christians are exasperated with the inability of the political process to halt America’s moral decline. Intercessors of America is a nonprofit group founded after Roe v. Wade to turn around America’s moral decline.

“We’ve taken over Congress from a Republican point of view, and not much has changed,” he said. “The nation’s morals continue to decline, we continue to spend more money than we take in, and it’s just a nation in crisis.”

The spiritual campaign has facilitated the creation of prayer groups and “Prayer at the Poll” events around the nation, encouraging Christians to pray regularly for America’s elected leaders and those running for office.

“When leaders understand that they answer to a higher power, they make different decisions, so it’s critical that we have leaders who have a fear and reverence toward God,” Mr. Kubal said. “A democracy can only be upheld by a virtuous populous, and we need virtuous, God-fearing leaders.”

Other prominent Christians have taken similar stances with regard to the 2016 race.

At a Wisconsin prayer rally on Wednesday, evangelist Franklin Graham said he did not trust either major political party’s candidate for president.

Instead, Mr. Graham repeatedly told the crowd that “the most important thing we can do today is pray for America,” All God’s People, a Christian blog, reported.

“Your vote matters; don’t stay home,” he said. “I’m not telling you who to vote for; God will tell you who to vote for.”

Polls suggest Christian voters aren’t thrilled with either major political party’s candidate for president.

An NBC News poll last month found that just 31 percent of evangelicals have a favorable opinion of Mr. Trump, compared to 19 percent who view Mrs. Clinton favorably.
